单选题If you do not use your arms or your legs for 1 , they will become weak; and when you start using them again, they will gradually become strong again. Everybody 2 this, and nobody would think of 3 the fact. Yet there are many people who seem 4 that the memory works in the same way. When someone says that he has a good memory, 5 really means that he 6 his memory 7 practice by exercising it very often, 8 consciously or unconsciously. When someone else says that his memory is 9 , he means that he does not give it enough chance 10 strong. The position is exactly the same as 11 of 12 people, one of whom exercises his arms and legs by playing balls, 13 the other sits in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own 14 . But if he tells us that he has a poor memory, many of us think that his parents are 15 , or that he is just 16 , and few of us realize that it is just 17 it was his arms or legs that were weak. Not all of us can become very strong in body or very clever 18 mind, but all of us can improve our strength and our memory by the same method. Have you ever noticed that people who cannot read or write usually have 19 memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always 20 .

单选题We experience different forms of the sun's energy every day. The sun is the major source of energy for our planet. It causes the evaporation(蒸发)of water from the oceans and lakes. Sunlight also provides the energy used by green plants to make their own food. Much of the energy that comes from the sun never reaches the earth's surface. It is either reflected or absorbed by the gases in the upper atmosphere. Of the energy that reaches the lower atmosphere, 30% is reflected by clouds or the earth's surface. The remaining 70% warms the surface of the planet, causes water to evaporate, and provides energy for the water cycle and weather. Only a tiny part, approximately 0.023%, is actually used by green plants to produce food. Many gases found in the atmosphere actually reflect heat energy escaping from the earth's surface back to the earth. These gases act like the glass of a greenhouse in that they allow energy from the sun to enter but prevent energy form leaving. They are therefore called greenhouse gases. When sunlight strikes an object, some of the energy is absorbed and some is reflected. The amount reflected depends on the surface. Dark-colored surfaces, such as dark soil or forest, absorb more energy.

单选题阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。{{B}}A{{/B}} When we do not understand each other's language, we can talk with the help of signs. A Frenchman was once travelling in England. He could not speak English at all. One day he went into a restaurant and sat down at a table. When the waiter came, he opened his mouth, put his fingers in it and took them out again. He wanted to say. "Bring me something to eat. " The waiter soon brought him a cup of tea. The man moved his head from side to side. The waiter understood him and took the tea away. In a moment he came with a cup of coffee. But the man again refused it. He shook his head whenever the waiter brought him something to drink, for drinks are not good. When the man was going away, another man came in. This man saw the waiter, and he put his hand on his stomach(胃). That was enough. In a few minutes there was a large plate of meat and vegetables on the table in front of him. So, you see, we cannot understand the language of signs as well as we can understand the language of words.

单选题In the passage the author's attitude towards "mixed-ability teaching" is ______.

单选题There are three branches of medicine, One is called "doctor medicine" or "scientific medicine". Scientific doctors try to observe sicknesses, look for logical patterns, and then find out how the human body works. From there they figure out what treatments may work. This kind of medicine is believed to date from the 4th century BC. Although nowadays it is successful, in the ancient world this approach probably did not cure many patients. The second kind of medicine is called "natural cures" or "folk medicine", in which less educated people try to cure sicknesses with various herbs(草). These folk healers also use observation and logic, but they are not aware of it. They try things until they find something that seems to work, and then they keep doing that. Folk medicine flourished long before the development of scientific medicine and was more successful in ancient times than doctor medicine. The third kind is called "health spas" or "faith healing". Sometimes this is as simple as touching the holy man and being immediately healed. Other times, a magician may make you a magic charm, or say a spell, to cure you. Some religious groups organize special healing shrines (神坛) for the sick. In these places people rest, get plenty of sleep, eat healthy food, drink water instead of wine, and exercise in various ways. They also talk to the priests and pray to the gods. If you are feeling depressed or you have been working too hard, going to these places may be just the right thing to make you feel better.
